Question

104. The area of the triangle formed by the
points (-2, 0) (0, -2) and (2, 0) is :
(1) 0
(2) 4
(3) 2
(4) - 4​

Answer 1

Answer:

4 sq units

Step-by-step explanation:

=》area of triangle =1÷2[x1(y2-y3)+x2(y3-y1)+x3(y1-y2)] use this formula

=》1÷2[-2(-2-0)+0(0-0)+2(0+2)

=》1÷2(4+0+4)

=》8÷2

=》4sq. units

I hope this answer is clear to you . thankyou

Answer 2

Correct answer : 4 unit sq.

Step-by-step explanation:

If, (x1, x2), (x2, y2) and (x3, y3) are the coordinates of vertices of triangle then

Area of Triangle = 1/2((x1(y2−y3)+x2(y3−y1)+x3(y1−y2))

therefore,

=1/2 ((-2 (-2-0)+0 (0-0)+(0-(-2)))

= 1/2 ((-2 (-2)+0+2 (2))

=1/2 (8)

=4 unit sq.
